A consulting engineering firm is preparing a preliminary cost estimate for a design-construct project of a coal processing plant. The firm, which completed a similar project in 2001 with a construction cost of $1,389 million, wants to use the ENR construction cost index to update the cost. Use the index value in 2001 = 116; index value in mid-2010 = 430 values to estimate the cost of construction for a similar-size plant in mid-2010.?
